Novel Pump-Fed Mechanical Back Brush

ABSTRACT

A hand held back brush has a rotating brush head and a reservoir for liquid soap from which the soap is actively vectored towards the skin via an active pumping mechanism.

This application is a continuation in parts of application Ser. No. 13,744,386 filed on Jan. 17, 2013 and application Ser. No. 13,766,792 filed on Feb. 14, 2013.

FIELD OF THE INVENTION

The field of the invention is toilet and bath accessories.

BACKGROUND OF THE INVENTION

There are several devices which use a hand held device to apply topical soaps and cremes to skin during bathing and otherwise. In U.S. Pat. No. 4,040,414, Suroff describes the use of an ultrasonic applicator tool to apply topical medication. In U.S. Pat. No. 6,662,386 Bowerman et al describe a wall mounted back brush unit where the brush and soap dispenser components are immobile and the bather has to back into the device while standing or sitting. In U.S. Pat. No. 6,170,108 Knight et al. describe a hand held electrically powered back brush. In U.S. Pat. No. 5,834,410, Slocum describes textured soap for massage an scrubbing effect.

OBJECTS OF THE INVENTION

One object of the invention is to develop a novel back brush. Another object of the invention is to develop a back brush which dispenses liquid soap via a pump.

SUMMARY OF THE INVENTION

The invention is a hand held back brush with built in pump delivered soap dispenser.

DETAILED DESCRIPTION OF THE INVENTION

The invention is a foot and a half in length. It has a curvature in the handle allowing for better reach during use. The handle has a soft elastomer with a thumb controlled control panel. A liquid soap is stored in the hollow cavity of the device all along the length of the device. A liquid soap booster is found near the motor in the head, and the head brush elements are replaceable.

The device is powered by a variety of means including mechanical, electrical and manual activated features. The device contains an active pumping system for the liquid soap which pressure dispenses the soap through the head of the brush.

EXAMPLES OF THE INVENTION

A hand held brush has a circulating brush element, and a long, curved plastic handle which is 18 inches in length and has a soap reservoir which feeds into a perforation at the center of the circulating brush head. The soap is fed by a peristaltic pump into the head and delivered to the brush area while in use. The brush elements are all made of thermoplastic polycarbonate with a clear panel over the soap reservoir which allows for visualization of the liquid soap.
